Error Log Section 6-2
Error Log Saving Area When an error is detected, it is saved, along with the time when the error
occurred, as an error in the CompoNet Master Board RAM.
Some errors are fatal and they are also saved in the EEPROM. Those error
logs saved in the EEPROM are retained even after the CompoNet Master
Board is shutdown or reset. The logs in the EEPROM are copied in the RAM,
when the CompoNet Master Board is started up.
The logs in the EEPROM are copied in the RAM, when the CompoNet Master
Board is started up.
It is only the error logs in RAM that can be read by reading function. But the
error logs both in RAM and in the EEPROM are cleared by clearing function.
Reading or Clearing the
Error Log Table The Error Log Tables can be read or cleared by the Detailed status group.
Precautions for Correct Use
To keep the time of error occurrence, the Board uses the time information
notified periodically by the user application.
When no time information is given by the user application, 0 is entered as the
time of error occurrence in the error log.
